You're the one trying to claim "more benefit to noncasters". I've given numerous examples proving considerable advantage to various casters by various means and methods.
You've yet to even describe *any* noncaster option that actually makes things decent for them. T4/5 to T1. Which classes? HOW? My examples turn them into casters (thus making them on par, sure, because now they're on the other side of the fence).
But a T1 class, by definition, can do all standard jobs in the party (damage dealer, tank, controller, skillmonkey, and whatever else you might need). And often better than T3 classes or below can do in their *specialties*. T2 can do most of that, but there's always gaps. T3 has an area where they rock the house about as well as a T1- but only in one area. And T4 and below just fail at life.
Make me any build you like, just one, that achieves T1 "anything you can do I can do better" status. Without using caster classes. And, yes, psionics and artificers qualify as casters.
Your goal is "clearly as good or better than a sorcerer". Bar is set. Prove your claim.
